DISPLAY DEVICE INCLUDING INORGANIC DEPOSITION LAYER ON LIGHT EMITTING ELEMENT - A simplified explanation of the abstract

This abstract first appeared for US patent application 17875299 titled 'DISPLAY DEVICE INCLUDING INORGANIC DEPOSITION LAYER ON LIGHT EMITTING ELEMENT

Simplified Explanation

The patent application describes a display device that includes various layers and electrodes to create a display with improved performance. Here is a simplified explanation of the abstract:

  • The display device consists of a substrate, a first electrode, a bank layer, a light emitting layer, a second electrode, an inorganic deposition layer, and a thin film encapsulation layer.
  • The first electrode is placed on the substrate, and the bank layer partially exposes the top surface of the first electrode.
  • The light emitting layer is then placed on the partially exposed top surface of the first electrode.
  • The second electrode is placed on top of the light emitting layer and the bank layer.
  • An inorganic deposition layer is added on top of the second electrode.
  • Finally, a thin film encapsulation layer is applied on top of the inorganic deposition layer.
  • The inorganic deposition layer has an absorption coefficient (k) of less than 4 at a wavelength of about 550 nm.

Potential applications of this technology:

  • This display device can be used in various electronic devices such as smartphones, tablets, televisions, and computer monitors.
  • It can also be used in wearable devices like smartwatches and augmented reality glasses.

Problems solved by this technology:

  • The display device provides improved performance and visual quality due to the specific arrangement of layers and electrodes.
  • The inorganic deposition layer with a low absorption coefficient helps in reducing light loss and enhancing the brightness of the display.

Benefits of this technology:

  • The display device offers a high-quality visual experience with improved brightness and contrast.
  • It provides better energy efficiency by reducing light loss.
  • The thin film encapsulation layer helps in protecting the display from external factors like moisture and dust, increasing its durability.


Original Abstract Submitted

A display device includes: a substrate; a first electrode on the substrate; a bank layer partially exposing a top surface of the first electrode; a light emitting layer disposed on the partially exposed top surface of the first electrode; a second electrode on the light emitting layer and the bank layer; an inorganic deposition layer on the second electrode; and a thin film encapsulation layer on the inorganic deposition layer, where at a wavelength of about 550 nm, an absorption coefficient (k) of the inorganic deposition layer is less than about 4.
